Ribbed slab (es-ES)

The rib reinforcement follows the same rules with the beam reinforcement. However, mainly as far as the stirrups are concerned, the amount of placed rebars is not as large as it is in beams. Between the ribs, the slab is usually reinforced with a common wire mesh.

In reality, sandwich slabs are ribbed slabs with a slab placed both to their upper and lower surface. Sandwich slabs may have the disadvantage of a larger weight compared to the ribbed ones but on the other hand, they have the advantage that their spans and supports behave in the same proper way.
